Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'S' confirms the SOIC surface-mount package variant rather than the standard DIP configuration. Confirm RoHS compliance status and check for obsolete or discontinued manufacturing notices from Fairchild Semiconductor or Broadcom, as this component family has been subject to lifecycle changes.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high density packaging is required alongside high gain performance. The split Darlington architecture offers superior speed compared to conventional photodarlington types. Ensure the operating environment remains within the specified 0°C to 70°C range for guaranteed performance parameters.
